It is already known to construct holders for lip sticks or cosmeticsticks in such a manner that the stick is screwed out from or down intothe holder by a rotation. The purpose is not only to feed forward thestick, when it has been worn, but also upon each use to screw down thestick into the holder to protect it against heat, deformation andsoiling of the habit and of the hands in case the cover might fall onunintentionally. However, experience shows that the screwingdown of thestick is frequently forgotten, because it requires an operation otherthan putting on the cover.

According to the present invention the screwing device and the cover areso designed that the putting on of the cover must necessarily beconnected with such a rotation that the stick is thereby screwed downinto protected position,.and the return rotation necessary to remove thecover causes the screwing-out of the stick into position for use. Inthis manner at each puttingon of the cover the stick is broughtautomatically into the position most favorable to its conservation, sothat its screwing-down into the holder cannot be forgotten. The holdermay also be so made that at each removal of the cover the stick is fedforward automatically an amount corresponding to the degree of wearwhich has taken place each time.

An embodiment of the invention is illustrated in the annexed drawings.Fig. 1 shows one half of an axial longitudinal cross section of theholder with stick on the line I-I of Fig. 4. Fig. 2 shows a similaraxial section on the line 2-2 of Fig. 4. Fig. 3 shows a partial sectionon the line 3--3 of Fig. 4. Fig. 4 shows a developed View of the lowerportion of the cover lining and of the inner cover sleeve. Fig. 5 showsan elevation of the stick holder after removal of the cover, some partsbeing broken away to show parts otherwise not visible. Fig. 6 shows anelevation of the cover proper, the most part of the exterior covermember 1 and some portion of the cover lining I I being broken away.

In Fig. 4 the lining I l of the cover 'I is shown in full lines and thesleeve I4 in dotted lines.

The lip stick is movable longitudinally in ordinary manner in anexterior holder in the form of a cylinder 2, the stick at its lower endbeing attached in a ring 3 having an exterior pin 4 which projects intoa steep helical groove 5 on the interior side of the cylinder 2. The pinprojects through an axial longitudinal guide of a turnable interiorsleeve 6. By turning the sleeve in one, or the other direction the lipstick is (Cl. 20G-56) moved preferably through about the stroke h(Fig. 1) upon rotating the sleeve 6 through about 1/s of a completerevolution. This arrangement is well known.

According to the invention the sleeve 6 may be 5 coupled to the cover 1to enable the stick being screwed by means of the cover. For thispurpose the sleeve 6 is bent outwards at 6a and downwards at 6b andprovided with pressed edge teeth 8 cooperating with teeth 9 made in the10 lower edge of inwardly bent lugs I0 of a lining II which is iixedlyconnected to the cover. The cover lining has one or more bayonet groovesconsisting of an axial portion I2 and a peripheral portion I2a. 15

The length of the groove portion I2a corresponds just to the stroke hand limits the turning movement of the cover 'I in one directionrelatively to the cylinder 2 by means of a pin I'3 attached therein andmeshing with the groove 20 portion I2a. The bayonet groove has furtheron the side opposite the portion I2a a short peripheral extension I2bjoining to the portion I2 through an inclined portion I2c.

When the cover 1 is put on, its groove portion 25 I2 moves axially overthe pin I3 downwardly until the top edge of the groove portion I2astrikes. against the pin. Then the cover is turned to the left (arrow20, Fig. 4) to iixed position, until the bottom of the groove portionI2a stops 30 against the pin I3. This rotation is transmitted by theteeth 9, 8 to the sleeve 6b, 6a, 6, pin ll and ring 3 on to the lipstick l' which owing to the helical groove 5 is withdrawn into thecylinder 2 (inner position). By an opposite rotation of 35 the cover Ito the right the pin I3 moves firstly in the groove portion I2a to aposition directly above the axial groove portion I2, whereby the stick Iis moved through the same stroke h outwards, but owing to the additionalgroove por- 40 tion I2b the cover may be further rotated to the left,until the left hand groove portion I2b strikes against the pin I3. Bythis additional rotation the stick I is fed forward through a certainamount. If then the cover is removed, 45 it is rstly moved somewhataxially, until the inclination I2c strikes against the pin I3. But thenthe coupling teeth 9, 8 have been separated from one another. During afurther axial movement of the cover the inclination I'2c slides rela.-5o tively to the pin I3 which imparts to the cover a small forwardrotation, however, now without rotating the sleeve 6 along with it. Thenthe pin iinally arrives into the axial groove portion I2 and permits thecomplete removal of the cover. 55

Cil

As will be seen, when the stick I is to be used and the cover 1 istherefore rotated back (released), always a greater rotation takes placethan at putting on the cover and effecting the forward rotation (lockingrotation) of the cover. Therefore the stick I is always fed forwardsthrough an amount which is as much greater than the stroke h ascorresponds to the additional groove I2b. l

However, in order to obtain automatically a forward feed of the stickcorresponding to the wear which has taken place each time, the followingspecial arrangement may be used: Inside the cover 1 there is a stickcontacting sleeve I4 forming a sort of interior cover and being slidablelongitudinally and also rotatable relatively to the cover 1. At the topa combined compression and torsion spring I5 is inserted between members1 and I4. The sleeve I4 has at one or more places stamped out in it alug I6 with a transverse tooth row I1 projecting into an opening I 8 ofthe lining II and located opposite a similar tooth row I9 4in the topedge Yof the opening I 8 but normally spaced so much therefrom axiallyas the above-mentioned special stick movement corresponding to thegroove extension I2b. The spring I5 tends to so move the sleeve I4 thatthe lug I6 is located at bottom and to the right in the opening I8 (Fig.4).

Now, the sleeve I4 has at its bottom portion an open recess I 9a, I9b,I9c of the same axial height as the groove I2 and of the sameperipheralI width (between I9a and I9c) as the groove I2a of the coverlining II, however having no extension corresponding to I2b. In case thetransverse tooth rows I1 and I9 have the same relative location as shownin Fig. 4, the grooves I2, I2a are located as shown relatively to therecess I9a, I9b, I9c.

This location is occupied by the member 1 relatively to the member I4,when the cover is removed, the spring I5 pressing the lug I6 against thebottom and the right hand side of the opening I8. As shown in Fig. 1 thestick I projects the normal amount for use out from the cylinder 2.

If now the cover 1, I4 is put on, so that the groove I2 embraces the pinI3, the stick point lifts the sleeve I4 to the` position of Fig. 1 incompressing the spring I5, whereby the tooth row I1 of the lug I6 entersin engagement with the tooth row I9 of the cover 1, II to connect themember 1 with the member I4 non-turnably. The top edge of the groove.I2a and that of the recess edge I 9b are in contact with the pin I3.Now the cover 1, I4 is so turned in the arrow direction into lockingposition that the right hand end of the groove I2a strikes against thepin I3 and the stick is thereby lowered just through the stroke h intoprotected position.

If the stick is to be used, the cover 1, I4 is released by being rotatedopposite the arrow direction 20, untilI the edge 19a contacts with thepin I3, the stick I being thereby raised again and the cover may beremoved.

But when the stick I has been somewhat worn owing to use and the cover1, I4 is then put on, the stick point now projecting correspondinglyless upward will not raise the sleeve I4 so much relatively to the covermember 1, II, whereby between the tooth rows I 1 and I9 there will existan axial distance exactly corresponding to the degree of wear of thestick, the members 1 and II being therefore not any more coupled to thesleeve I4.

Then, the cover 1, I4, after having been locked (in arrow direction 20),is site arrow direction 26), whereby the edge I9a strikes firstlyagainst the pin I3 and prevents a further rotation of the sleeve I 4,but the cover 1, I I may be turned forth, the stick I and the sleeve I4with lug I6 being thereby further raised, until the tooth rows I1 and I9engage one another, and only then the further rotation is stopped. Thepin I3 now projects into the extension I2b to a degree corresponding tothe degree to which the stick I has been worn. Consequently the stickhas been fed forward through the correct amount. Then the cover mayagain be removed, whereby the spring I5 restores the relative locationof the members 1, II and I4.

In this manner an automatic forward feeding of the stick is alwaysobtained which corresponds to the actual wear.

Obviously the recess edge ISC may be shaped in any manner and may alsobe cut away, because that edge has no function. Also the size of theextension I2b is unimportant provided it is at least equal to theperipheral movement corresponding to the greatest distance between thetooth rows I1 and I 9 in Fig. 4.
